Hi:

I need to write a function which accepts a url as string. The function should do the following:

If the input is of the first url pattern, it should get the content after the last '/' in the url and before the .apk

If the input is of the second url pattern, it should get the content after the ?id= and before &feature


ie; in short, it should be returning package name from url. How can I accomplish this through java? Any help is appreciated.

 s = s.replaceAll(".*/([^&]+).*", "$1").replaceAll(".*=(.*)", "$1");

Open in new window

The above is possibly OK, although it should be possible to do it more elegantly

Well you didn't ask for that ;)

Quick and dirty - tack this on at the end

.replaceAll("\\.apk$", "");
